I have received invitations from many to join many, many others, but I find that following more than two or three is deadly time-consuming. So now I am basically using LinkedIn, Plaxo and Picasa. I seldom pop up on Dopplr and have relinquished other networks I have been in. LinkedIn is more popular and provides good links with people (I have well passed 100 connections), Plaxo has facilities such as updating your address book with the information provided by the people, so that you are always up to the last address change, and you also receive good birthday reminders (killer features to me). And, well, Picasa is useful for an amateur photographer like me.

I really wonder about other people's take on this. Do you share my views, have suggestions, would like to provide more advice? Please write me at <strong>social networks@ piana.eu</strong> (delete the two spaces). I will stay up for a few months, just to collect ideas, if you oblige. If you indicate your willingness to do so, I could publish the most interesting comments with or without your name.
